2.0 DISCUSSION

Affected Instruments: Valve 9355A, POS-303, POS"1044,SV-370, AIR-I-1-670A, and

ERFDS MUX 01/22/02

2.1 The devices included in Loop Test 11-11 collectively function toprovide a method of obtaining a liquid sample from the pressurizer.Valve 9355A will close on a Containment Isolation Phase "A" signal.

2.2 Calibration is achieved by bench setting the valve and setting theposition switches to specified position.

2.3 POS-303, POS-1044, and SV-370 are environmentally qualified.

2.4 Valve 9355A is time tested in the closed direction per STP V-3S1.

Based on full stroke of 7/16", POS-303 is set at 10 +0, -5'.of travel from the full closed position. This is equivalentto 1/16 +0, -1/32".

Based on full stroke of 7/16", POS-1044 is set at 90 ~ 5~ oftravel from the full closed position. This is equivalent to3/8 k 1/32".

Maximum valve dp: 2504 PSI (Upset, Emergency Node)(Ref 3.8).

Specific Start to Open Pressure: 9 PSIG (Ref 3.6)

6.1.8 Maximum Case Pressure: 80 PSIG (Ref 3.9)

For valve and regulator calibration a 0.5~ test gauge of appropriate rangemay be used. Therefore, a 0-60 a 0.3 PSIG test gauge is appropriate.

9. 0 CONCLUSION

A valve full closed functional limit of ~ 6.0 PSIG will ensure therequirement in Section 4.2.2 is met. Setting POS-303 at ~ 1/16" fromvalve full closed will ensure consistent results for the valve timingtest. This will satisfy the requirement specified in Section 4.1. Thevalve is verified to fully open s air supply. 'This satisfies therequirement of Section 4.2.1.

Current plant scaling was corrected. The previous seating criteria(1 PSIG) was based on a soft seat, however, seating criteria was correctedto 3 PSIG due to Valve 9355 having a stellite seat (Ref 3.6). This willincrease the seating force of the valve in a conservative direction.
